BOTANICAL CLASSIFICATION

Lagerstroemia: L. indica×L. fauriei×L. limii. ‘Tonto’×L. indica ‘Catawba’

CULTIVAR DENOMINATION

Crapemyrtle ‘Tishomingo’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of the ornamental flowering shrub and landscape plant of the genus Lagerstroemia, commonly known as crapemyrtle, of the family Lythraceae, and is referred to hereinafter by its cultivar denomination ‘Tishomingo’. This novel plant is an asexually propagated hybrid of crapemyrtle that was selected in 2008 from approximately 2800 crosses. The female seed parent is Lagerstroemia indica×L. fauriei ‘Tonto’ (unpatented). The male pollen parent is Lagerstroemia indica ‘Catawba’ (unpatented).

‘Tishomingo’ was selected for its unique purple flower color and medium to large growth habit. The designation ‘Tishomingo’ was evaluated under the experimental name ‘2008-0001’. This high quality novel and distinct cultivar of crapemyrtle plant was vegetatively propagated at the Mississippi State University Coastal Research and Extension Center, South Mississippi Branch Experiment Station, in Poplarville, Miss. Each of several generations of cuttings has produced stable plants identical to the original seedling plant.

SUMMARY OF THE INVENTION

The new cultivar is a Lagerstroemia hybrid resulting from the cross of Lagerstroemia: L. indica×L. fauriei×L. limii ‘Tonto’ (female parent)×L. indica ‘Catawba’ (male parent). ‘Tishomingo’ is a distinctive, new cultivar of crapemyrtle plant characterized by its purple flower color and medium to large crapemyrtle growth habit. The traits of the new plant are continually maintained when propagated asexually. This new cultivar may vary slightly with changes in location, temperature, light, and other environmental conditions, but the genotype will not be affected. ‘Tishomingo’ also exhibits the quality and characteristic of adaptability to all areas of hardiness zones 7-10. ‘Tishomingo’ is much taller than its female parent ‘Tonto’ and its male parent ‘Catawba’. ‘Tonto’ is a large shrub ranging from 5 to 10 feet in height. ‘Tonto’ has red to fuchsia flowers and maroon fall color. ‘Catawba’, the male pollen parent, is a small-sized crapemyrtle averaging 8 to 10 feet in height. ‘Catawba’ has violet purple flowers and red orange fall color. Flower color for ‘Tishomingo’ is more purple than either parent. This new plant has unique flower color contained in a medium to large growing crapemyrtle. The combination of ‘Tishomingo's purple flower color and medium to large growth habit distinguishes it from all other crapemyrtle cultivars.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

Latin name: Lagerstroemia×‘Tishomingo’

Lagerstroemia: L. indica×L. fauriei×L. limii. ‘Tonto’×Lagerstroemia indica ‘Catawba’

Cultivar denomination: ‘Tishomingo’

The present invention is a novel Lagerstroemia×‘Tishomingo’ cultivar known as ‘Tishomingo’ that is different from other crapemyrtle cultivars.

TON X CAT 0001 Row 01—Replication 1—Plant # 1 in Rep. McNeill planting.

The following is a detailed botanical description of the characteristics of the new Lagerstroemia crapemyrtle cultivar known as ‘Tishomingo’, based on observations of the plant grown at the Coastal Research and Extension Center and research facility at Poplarville, Miss., and under similar conditions to those for growing these plants commercially. ‘Tishomingo’ has been observed under many but not all possible environmental conditions. Color notations of plant tissues are based upon The Royal Horticulture Society (R.H.S.) Colour Chart, 2001 Edition. Color notations may have been slightly affected by light quality and fertility and general plant growth. Certain characteristics will vary depending on the age of the plants so that dimensions, sizes, and colors are approximations or averages since the cultivar has not been observed under every possible environmental condition. Therefore the phenotype of the cultivar may differ from the descriptions depending upon environmental variations including, but not limited to, the season, temperatures, day lengths, light direction and quality, and fertilization, as well as other factors.

The present invention is a Lagerstroemia hybrid resulting from the cross of Lagerstroemia: L. indica×L. fauriei×L. limii. ‘Tonto’ (female parent)×Lagerstroemia indica ‘Catawba’ (male parent). The stem color of this new plant is Royal Horticulture Society (R.H.S.) Colour Chart Group 176-A. The leaf color is R.H.S. Colour Chart Group 138-A. The flower petal color is medium to dark purple (R.H.S. Colour Chart Group N78-A). This new plant is a crapemyrtle with unique purple flower color that may be used as a specimen in landscapes where crapemyrtles are traditionally used. This crapemyrtle plant will be in the fifteen plus (15+) foot range for growth. Currently, not many crapemyrtles exist that are “deep purples” and that are in this growth range.

FIGS. 1 and 2 show the flower color and the leaf color of the new cultivar. FIG. 3 shows the leaf color and stem color of the new cultivar. FIG. 4 shows the leaf color and stem color of the new plant.

The final height and width of the plant have not been observed. Three-year plants in the research facility at the South Mississippi Branch Experiment Station are greater than fifteen (15) feet tall and approximately 6 to 8 feet wide, forming a multiple or single trunk large crapemyrtle. It can possibly be grown as a medium to large shrub in climates where shoot growth is killed to the ground each winter. Its foliage comprises glossy green leaves that are opposite and that are approximately from 2.50 to 3.00 inches in length and from 1.00 to 1.50 inches in width. The leaf top color is R.H.S. Colour Chart Group 138-A. The leaf underside color is R.H.S. Colour Chart Group 146-A. The leaf type is simple and is persistent and deciduous. The leaf margin is entire, the leaf shape is elliptical, and the leaf venation is pinnate. The stem is rather slender with a slightly angular shape with prominent wings when young and a round shape when growth is more mature. The new plant is a deciduous, summer-flowering plant, so that fall color has been inconsequential. The plant has shown insect and disease tolerance comparable to the parents under field conditions.

The flowers are perfect, 6-petaled and each flower is approximately 1.30 inches in diameter. The flowers are purple and are most typically visible from early June to late August depending on environmental conditions. The flowers have medium tapered panicles. The flower panticle is approximately 9 to 11 inches long. The unopened flower capsule color is R.H.S. Colour Chart Group 59-A. When the flowers fade, they generally fade to lighter shades of purple, lavender, or light blue, and not to pink or red tones.

The fruit is comprised of seed pods that are dark green in color turning to brown. The mature seed pod color is R.H.S. Colour Chart Group 144-A. The fruit is a broad-ellipsoidal 6-valved dehiscent capsule, brown in color, approximately ½ of an inch wide. Seeds are approximately ⅜ to ½ of an inch long and winged. The pistil color is R.H.S. Colour Chart Group 14-A. A woody capsule generally persists on the panicle until late winter. Cold testing for cold hardiness has not yet been completed for the new cultivar. Plants had just begun to exhibit the exfoliating bark characteristics common to crapemyrtles at the time of observation.

Rooting of the new medium to large-sized crapemyrtle is easily accomplished, making the plant excellent for production purposes, and such rooted plants are identical to the original. The novelty of the plant includes its purple flower color (R.H.S. Colour Chart Group N78-A) and its large size. ‘Tishomingo’ may be used as a specimen in landscapes where crapemyrtles are traditionally used. The new crapemyrtle plant will be in the fifteen plus (15+) foot range for growth. Currently, not many crapemyrtles exist that are this “deep purple” color and that are in the medium to large crapemyrtle group growth range.

As will be apparent to those skilled in horticultural science, the new and distinct crapemyrtle plant cultivar described herein may vary in minor detail due to climatic, soil, and cultural conditions under which the variety may be grown, as well as the stage of growth. 

What is claimed is:
 1. A new and distinct cultivar of crapemyrtle Lagerstroemia hybrid plant named ‘Tishomingo’, substantially as herein illustrated and described.
